If you knew how many 'processed foods' were one molecule away from inedible products you wouldn't set foot in a grocery store. Homogenized milk is not fit for human consumption. Canned goods are loaded with chemicals from the metal of the cans. Microwaved anything in plastic or cardboard and you have chemical enriched food. The truth about our foods today is out there but there is no dollars in printing the facts. If you have processed deli meats or frozen steam in the bag vegetables in your fridge then no use giving up margarine.
